This may provide a possibility to infer central processes from observed phasic heart period responses (HPR). Currently, operational methods are used for HPR analysis. These methods embody implicit assumptions on how central states influence heart period. Here, we build an explicit psychophysiological model (PsPM) for event\u2010related HPR. This phenomenological PsPM is based on three experiments involving white noise sounds, an auditory oddball task, and emotional picture viewing. The model is optimized with respect to predictive validity\u2014the ability to separate experimental conditions from each other. To validate the PsPM, an independent sample of participants is presented with auditory stimuli of varying intensity and emotional pictures of negative and positive valence, at short intertrial intervals. Our model discriminates these experimental conditions from each other better than operational approaches. We conclude that our PsPM is more sensitive to distinguish experimental manipulations based on heart period data than operational methods, and furnishes a principled approach to analysis of HPR.<\/jats:p>","DOI":"10.1111\/psyp.12622","type":"journal-article","created":{"date-parts":[[2016,2,5]],"date-time":"2016-02-05T14:52:08Z","timestamp":1454683928000},"page":"837-846","source":"Crossref","is-referenced-by-count":35,"title":["Modeling event\u2010related heart period responses"],"prefix":"10.1111","volume":"53","author":[{"given":"Philipp C.","family":"Paulus","sequence":"first","affiliation":[{"name":"Department of Psychiatry Psychotherapy, and Psychosomatics, University of Zurich Zurich Switzerland"},{"name":"Neuroscience Center Zurich, University of Zurich Zurich Switzerland"},{"name":"Department of Psychology Technische Universit\u00e4t Dresden Dresden Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Castegnetti","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Psychotherapy, and Psychosomatics, University of Zurich Zurich Switzerland"},{"name":"Neuroscience Center Zurich, University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominik R.","family":"Bach","sequence":"additional","affiliation":[{"name":"Department of Psychiatry Psychotherapy, and Psychosomatics, University of Zurich Zurich Switzerland"},{"name":"Neuroscience Center Zurich, University of Zurich Zurich Switzerland"},{"name":"Wellcome Trust Centre for Neuroimaging, University College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,2,5]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsycho.2006.08.005"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsycho.2014.08.006"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsycho.2010.06.007"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jneumeth.2009.08.005"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpsycho.2010.01.005"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8986.2012.01483.x"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpsycho.2010.01.011"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsycho.2013.09.010"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0131065"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8986.1993.tb01731.x"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8986.1995.tb03308.x"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1017\/CBO9780511546396.008"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1037\/1528-3542.1.3.276"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1177\/0049124104268644"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/1469-8986.3830474"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1172-12.2012"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/hbm.460010207"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8986.1978.tb01422.x"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1038\/npp.2013.40"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8986.1985.tb01649.x"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1027\/\/0269-8803.13.2.83"},{"key":"e_1_2_6_23_1","volume-title":"International Affective Picture System (IAPS): Affective ratings of pictures and instruction manual","author":"Lang P.
